## Which of the following helps identify leaves as monocot or dicot? A) Monocot leaves have parallel veins; dicot leaves have a network of veins. B) Monocot leaves are arranged alternately on the stem; dicot leaves are arranged opposite one another on the stem. C) Monocot leaves are wide; dicot leaves are narrow.

[ad_1]

Answer:

The correct answer would be option A. Monocot leaves have parallel veins; dicot leaves have a network of veins.

Explanation:

Monocots are the plants having only one cotyledon or seed with only one leaf also called monocotyledons. Dicots are the plants having two cotyledons or seed with two leaves.

Monocots and dicots have few characters that make them easily recognizable such as venation pattern: The arrangement of veins in a leaf is called the venation pattern; dicots have a reticulate or network of veins type venation, while monocots have parallel venation.

Thus, the correct option would be A.

[ad_1]

This problem is to apply Roult’s Law.

Roult’s Law states that the vapor pressure, p, of a solution of a non-volatile solute is equal to the vapor pressure of the pure solvent, Po solv, times the mole fraction of the solvent, Xsolv

p = Xsolv * Po sol

X solv = number of moles of solvent / number of moles of solution

The solvent is water and the solute (not volatile) is glycerin.

Number of moles = mass in grams / molar mass

mass of water = 132 ml * 1 g/ml = 132 g

molar mass of water = 18 g/mol

=> number of moles of water = 132 g / 18 g/mol = 7.33333 mol

mass of glycerin = 27.2 g

molar mass of glycerin:, C3H8O3: 3 * 12 g/mol + 8 * 1 g/mol + 3*16 g/mol = 92 g/mol

number of moles of glycerin = 27.2g / 92 g/mol = 0.29565

total number of moles = 7.33333 moles + 0.29565 moles = 7.62898 moles

=> X solv = 7.33333 / 7.62898 = 0.96125

=> p = 0.96125 * 31.8 torr ≈ 30.57 torr ≈ 30.6 torr.

Answer: 30.6 torr

## If the telescope is 1 m deep and 8 m wide, how far is the focus from the vertex? 1 2 4 16 Find the vertex, focus, directrix, and focal width of the parabola. negative 1 divided by 12 times x squared = y

[ad_1]

First, let me introduce the general equation of the parabola:

(x-h)^2 = +/- 4a(y-k) or (y-k)^2=+/- 4a(x-h), where

(h,k) are the coordinates of the vertex
a is the distance of the vertex to the focus
4a = length of lactus rectum or the focal width

If the equation contains (x-h)^2, then the parabola passes the x-axis twice. Similarly, (y-k)^2 passes the y-axis twice. If the sign is (-), it opens to the left(if y-axis) or downward (if x-axis). If the sign is (+), it opens to the right(if y-axis) or upward (if x-axis).

The equation of the parabola is -1/12 x^2 = y. Rearranging to the general form:

x^2 = -12y
Therefore,

-4a = -12
4a = 12
a = 3, and the parabola is facing downwards.

The vertex is (0,0) at the origin.
The focus is (0,-3). Since it is negative, the focus is situated downwards, hence -3.
The directrix is the mirror image of the focus. Hence, it is a line passing +3 on the y-axis. y=3
Focal width is 4a which is equal to 12 units.

This problem is to apply Roult’s Law.

Roult’s Law states that the vapor pressure, p, of a solution of a non-volatile solute is equal to the vapor pressure of the pure solvent, Po solv, times the mole fraction of the solvent, Xsolv

p = Xsolv * Po sol

X solv = number of moles of solvent / number of moles of solution

The solvent is water and the solute (not volatile) is glycerin.

Number of moles = mass in grams / molar mass

mass of water = 132 ml * 1 g/ml = 132 g

molar mass of water = 18 g/mol

=> number of moles of water = 132 g / 18 g/mol = 7.33333 mol

mass of glycerin = 27.2 g

molar mass of glycerin:, C3H8O3: 3 * 12 g/mol + 8 * 1 g/mol + 3*16 g/mol = 92 g/mol

number of moles of glycerin = 27.2g / 92 g/mol = 0.29565

total number of moles = 7.33333 moles + 0.29565 moles = 7.62898 moles

Answer:

Noninvolvement in world affairs is termed “isolationism”.

Explanation:

Isolationism is a concept that designates a political inclination that defends the isolation and nonintervention of a country in international conjunctural issues. That is, putting it in simpler terms, isolationism proposes that a country does not intervene in any way in an external conflict that afflicts another nation or group of nations so that it does not end up affecting their interests.

Basically, isolationism causes that the country that adopts this position is totally isolated from everything that happens in the rest of the world so that nothing affects it in its possible benefits.

In the aftermath of World War II, the influence of the Soviet Union extended through the countries that were invaded by fascists in the Eastern Front, such as Poland, Hungary, and Bulgaria.

Poland

In January 1947, elections were held, resulting in the communist Republic of Poland. Previously elections were intervened so the communist candidates could turn victorious, and the members of communist resistance continued to resist in the territories near to Ucrain but fierce soviets intervention turned to mass arrest where all kinds of executions, deportations, and imprisonment took place.

Hungary

In Hungary, the Soviets imposed harsh conditions that seized key raw materials and interfered in the internal affairs and social, policymaking. The Red army set some vigilance with police to persecute political opponents and enemies of the state.

Bulgaria

In September 1944, The Soviets declared war on Bulgary, under the argument that this country allowed its territory where the Wehrmacht (Germany) crossed and continued to press the frontlines eastwards. The Red Army motivated a coup d Etat where communists also set favorable conditions for the creation of a communist regime.

-This countries became to form the Eastern bloc, a period that lasted several decades until the 1989 Revolutions set an important amount of political and social changes in Europe in East and Central Europe, causing most of the socialist states, formerly puppet states to Soviet Russia to collapse and engage in democratic process and incorporate a different economic model.

The Contribution Margin per unit (CM) can be calculated
from the difference of Selling Price per unit (SP) and Total Expenses per unit
(TE).

First, let’s calculate the value of SP:

SP = Sales / Units sold

SP = \$1,043,400 / 22,200 units sold

SP = \$47

Second, calculate all expenses:

Direct materials per unit = \$234,948 / 27,970 units
manufactured = \$8.4

Direct labor per unit = \$131,459 / 27,970 units
manufactured = \$4.7

Variable manufacturing overhead per unit = \$240,542 / 27,970
units manufactured = \$8.6

Variable selling expenses per unit = \$113,220 / 22,200
units sold = \$5.1

TE = \$26.8

Therefore the CM is:

CM = SP – TE

CM = \$47 – \$26.8

CM = \$20.2 per unit

Hello! Okay let me start off by explaining to how you can simplify a square root…

Let’s take √12 for instance…

the factors of this number are 2, 3, 4, and 6 …. and out of these 4 numbers there is one perfect square, which is 4

so you can split √12 into —> √4 and √3  ….. these would then simplify into 2√3
because the 4 is square rooted

now by doing the same to √18 we get —-> √9 * √2 —->  3√2

Before we multiply the square roots we must remember that numbers underneath the square root can only be multiplied with other numbers underneath a square root….
so…

2√3 * 3√2
(2 * 3) * (√3 * √2)
6√6   <———————– This is your final answer!

I hope this helps! 😀

Charlie had a waist circumference of 47 inches and a BMI of 29 this shows that she is overweight. BMI test level is high from normal ranges shows that she is at higher risk of disease. She should lose weight and concern to the doctor.

Further Explanation:

Body mass index (BMI) is a measured value derived from the height of a person and mass. BMI indicates whether the person is healthy or overweight mainly used by physicians.

• Range of BMI in a normal person is 18.5-25 • Range of BMI in skinfold person is 25-30 • Range of BMI in underweight person is 15-18.5 The skinfold measurement test is used to determine a person’s body fat percentage and body composition.

In this test, we are the proportion of body fat by determining skinfold thickness at pinches specific part of the body. The estimate of these folds is determined the fat beneath the skin, also called subcutaneous adipose tissue.

The tester pinches the skin at the site and drags the fold of skin away from the muscle so only the fat tissue and skin are being held. The skinfold thickness is measured by skinfold calipers in millimeters.

Skin test includes the seven locations of the body:

1. Triceps

2. Quadriceps

3. Suprailiac

4. Pectoral

5. Subscapular

6. Midaxilla

7. Abdomen

Answer:

Option C – BD=76 cm

Step-by-step explanation:

Given : You are designing a diamond-shaped kite. you know that AD = 44.8 cm, DC = 72 cm, and AC = 84.8 cm.

To find : How long BD should it be?

Solution :

First we draw a rough diagram.

The given sides were AD = 44.8 cm, DC = 72 cm and AC = 84.8 cm.

According to properties of kite

Two disjoint pairs of consecutive sides are congruent.

So, AD=AB=44.8 cm

DC=BC=72 cm

The diagonals are perpendicular.

So, AC ⊥ BD

Let O be the point where diagonal intersect let let the partition be x and y.

AC= AO+OC

AC= …….

Perpendicular bisect the diagonal BD into equal parts let it be z.

BD=BO+OD

BD=z+z

Applying Pythagorean theorem in ΔAOD

where H=AD=44.8 ,P= AO=x , B=OD=z  ………

Applying Pythagorean theorem in ΔCOD

where H=DC=72 ,P= OC=y , B=OD=z  …………

Subtract  and    ……….

Add equation  and , to get values of x and y   Substitute x in   Substitute value of x in equation , to get z     We know, BD=z+z

BD= 38.06+38.06

BD= 76.12

Nearest to whole number BD=76 cm

Therefore, Option c – BD=76 cm is correct.

Explanation:  Animals, however well preserved and bred in conditions that are not in nature, that is, not in their natural habitat, animals still retain the animal instinct. Thus, young animals in the wild can be met daily, except for members of their species, and members of all other species, including predators, as well as humans. This means that in the natural environment, young animals can find themselves in a variety of dangers on a daily basis, but not only that. In this way young animals develop their ability to survive, escape from predators, manage, and develop their hunting skills, etc. All this is essential for socialization because according to all these developed skills and abilities their socialization depends. To deny any of the conditions prevailing in the wild means to deny the development of any skill or instinct, to deny proper socialization.
